A2.0-kg piece of steel with a temperature of 70 degree C is submerged in 1.0 kg of water at 15 degree C. At what temperature does the water/metal system reach equilibrium? The specific heat of steel is 0.107 cal/(g*K). Specific Heat of water is 4185 J/(kg*K.( The answer is 27 C)
HOW? I keep getting 70 degree C when I do m*C*delta T (of steel) = m* C* delta T (of water)

95.0 mL of H_2O is initially at room temperature (22 degree C). A chilled steel rod at 2 degree C is placed in the water. If the final temperature of the system is 21.3 degree C, what is the mass of the steel bar?

80.0 mL of water is initially at room temperature (22degrees C). A chilled steel rod at 2 degrees C is placed in the water. If the final temperature of the system is 21.2 degrees C, what is the mass of the steel bar?

A piece of metal of mass 112g is heated 100 degree C.,and dropped into a copper calorimeter of mass 40g containing 200g of water at 16 derreC. Neglecting the heat loss, the specific het of the meatal is nearly,if the equilibrium temperature …
